Whatdigitalcamera reviews the Sigma 50-200mm F4-5.6 DC OS HSM and writes;“Real-world testing produced some very nice pictures from this lens. There are no exceptional strengths to the Sigma 55-200mm but neither does it have any serious weaknesses. Given its low cost, there is little to fault and much to admire about this refreshingly unpretentious lens.”Rating:

Ephotozine reviews the Sigma 50-200mm F4-5.6 DC OS HSM and writes;“This isn’t an expensive lens, and although it isn’t the highest resolution lens I’ve tested, the results will be acceptable for most people, especially those who rarely produce large prints. The Optical Stabilisation system featured on this lens is very effective indeed when used with the correct technique, allowing sharp shots of static subjects that would otherwise not have been possible without flash, or additional lighting.”Rating:

Sigma 50-200mm F4-5.6 DC OS HSM User Reviews

Sigma 50-200mm OS lens | Rating:“This lens seems to be very good. Barrel and pin cushion aren’t even noticeable, bokeh is very nice, and the lens seems quite sharp in the limited tests I’ve done so far.” – by gary h

Good budget telephoto option | Rating:“Sigma has delivered very good product in this segment, much better than the cheapo 55-250mm from Canon. Good build, nice features (HSM, IS, IF design). And the lens is sharp in lower focal lengths and good bokeh. Only downside is that the lens is not sharp at longer focal lengths, but still very usable. “ – by Adhi

Does not measure up. | Rating:“I bought this lens to replace a 55-250mm from Canon that I gave away. After using the lens for awhile it does not measure up to the 55-250mm. The colors produced don’t look real. I guess it will be put on the shelf and not used. This will be my last non-Canon lens. I am not an expert but I don’t have any problems with a Canon lens. “ – by Flytyer

Sigma 50-200mm F4-5.6 DC OS HSM Specifications

This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function. The lens incorporates SLD (Special Low Dispersion) glass in the front lens groups and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures quiet and high-speed auto focus. The OS (Optical Stabilizer) function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds up to 4 stops slower than normal for steady, handheld photography. For Sony and Pentax mounts the built-in OS System allows the photographer to see the stabilized image in the viewfinder and can be used as an alternative with cameras having built-in image stabilization. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range. This lens has a minimum focusing distance of 43.3inches (110cm) throughout the entire zoom range and a maximum magnification ratio of 1:4.5. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters.
